When you buy 1000 CPU the failure rate of 4% every year.
That gives you statistically 40 dead servers each year for 5 years (avg component guaranteed life). thats 200 dead cpus.
Lets say $1000 per cpu thats $1,000,000 cost and $200,000 loss to damage.
1% - 50 dead CPU in 5 years - $50,000 in losses
In this scenario you have $150,000 to save or spend to get better equipment.
Also an important note. On top of that you suffer downtime losses and manpower cost of taking server out and swapping parts. If your eCommerce goes offline that might cause significant monetary loss.
For any large scale purchases its all about the numbers game.
In case of single purchases. Paying extra to get form 4% to 1% seems excessive (depending on the cost increase).
At this percentage levels its a roll of dice if it dies or not.
- Dylan16807 6y agoThat wasn't supposed to be a per year failure rate. 20% per 5 years is a crazy amount. Divide the numbers by 5 to get a per-year failure closer to my intent. So if it's $850 for the 4% failure chip, and $1000 for the 1% failure chip, I'll probably buy the cheaper one in bulk. $850k upfront and $34k in replacement, vs. $1000k upfront and $10k in replacement. There's extra manpower, sure, but even if it costs a hundred dollars of labor per replacement the numbers barely budge. > downtime losses In a big system you shouldn't have those from a single server failure! Downtime losses are the point I was making. As someone buying just one drive or chip, failure costs me massive amounts beyond the part itself. But if I can buy enough for redundancy, then those problems become much much smaller. If you're running things off one server, then apply the single device analysis, not the bulk analysis.
